Isaac’s last stand

Isaac entered Arkansas as a tropical storm early Friday, Aug. 31, and was quickly downgraded to a tropical depression. The first part of the storm brought much needed water to the state in a slow steady rain, but within 12 hours began throwing more intense flooding rains. Isaac produced one more stormy burst as it dragged the last of its spiral arms across the middle of the state, spawning severe thunderstorms and some spectacular skyscapes.
